Function

Troponin T is the tropomyosin-binding subunit of troponin, the thin filament regulatory complex which confers calcium-sensitivity to striated muscle actomyosin ATPase activity.

Subcellular Localization

Disease Associations

Arthrogryposis, distal, 2B (DA2B) [MIM:601680]: A form of distal arthrogryposis, a disease characterized by congenital joint contractures that mainly involve two or more distal parts of the limbs, in the absence of a primary neurological or muscle disease. DA2B is characterized by contractures of the hands and feet, and a distinctive face characterized by prominent nasolabial folds, small mouth and downslanting palpebral fissures. {ECO:0000269PubMed:12865991}. Note=The disease is caused by mutations affecting the gene represented in this entry.

Tissue Specificity

In fetal and adult fast skeletal muscles, with a higher level expression in fetal than in adult muscle.
